    a = £4.245, c = £2.455

    Step-by-step explanation:

    a + c = 6.70

    a = c + 1.79

    replace a in the first equation with c + 1.79

    c + 1.79 + c = 6.70

    simplify: 2c + 1.79 = 6.70

    subtract 1.79 from each side: 2c = 4.91

    divide each side by 2: c = 2.455

    now replace c in the second equation with 2.455

    a = 2.455 + 1.79

    add: a = 4.245
